A job only ever has one notification type. This is the first deploy, where the columns are added and populated. Next a data migration will happen to populate these new columns for the older jobs that do not have the values set. Then we stop populating the old columns and remove them. This refactoring of the table structure will make the queries to the table much easier to handle.
